After an enlightening discussion at the Programmatic Marketing Summit in January, Kerel Cooper, the head of advertising at Group Black, returned to the latest episode of the Marketing Mixer Podcast to delve deeper into his ongoing mission to highlight the outdated programmatic media buying practices that put Black-owned media companies at a disadvantage.
In collaboration with ad verification company Double Verify, Group Black conducted research that demonstrates the extent to which ad inventory on Black-owned media platforms is excluded from media budgets when basic tools like keyword blocklists and domain-level categorization are utilized in media purchases.
Cooper is now actively working with Double Verify to raise awareness about these findings, educating advertisers, and collaborating with industry associations to establish guidelines that prevent the exclusion of Black-owned media from programmatic spending.

Highlighted below are key takeaways from the conversation, presented in a concise and edited format for clarity.
